This is confusing to the user level applications like File Browser since the partition label will remain there for a long time. - Steps to reproduce ================== 1. Upgrade to kernel later than 5.9.0-rc3 2. Plug the external card reader and insert the formatted memory card 3. Verify if the memory card mounted and visible on File Browser 4. Remove the memory card from the card reader 5.
